How big are animals, really?

[Blockcaver]

The arrow that I shot my polar bear with (9’ and 25-5/16” skull) has frozen blood on it from the tip of the broadhead for about 28” to the back end of vanes. The arrow just had the nock end sticking out of hair and the broadhead buried in the far shoulder. Was virtually broadside at the shot.

Shot with a 65# compound at 29-1/4” draw with one of the evil 3-blade over-the-top 1-1/2” Spitfire broadheads NAP has made for 25 years. The Inuit guide said they had never seen a bear go down so fast….a few seconds.

This ^ one was about 42" wide through the chest. They say 2,000# on the hoof but that seems high.

This one was about the same. I'm 6'3 230# here, my buddy is 6' 180#, we are both right up against the bulls....no sitting back six feet behind them.
These Buff are in a whole different category; 1 1/4" thick overlapping ribs, heck you have to shoot through a hide that 1 1/2" thick, then 8" of muscle before you even get to the ribs......

Real question here: you stated 42” wide through the chest. Your arrow is wider than the buff, and both the bows from cam to cam is significantly longer than either animal is wide through the chest; is your bow a 50+ inch ATA model?
